2017A aluminium alloy is a heat treatable, wrought aluminium product which includes the significant addition of copper as an added alloying element. The material offers an attractive combination of high strength with excellent fatigue resistance. 2017A offers good corrosion resistance though traditional welding is not possible as the corrosion resistance characteristics would be affected. The alloy can only be welded using resistance welding techniques. With superior strength, ductility and formability, 2017A aluminium is commonly used in engineering applications. The material also offers greater strength when compared to 2011 aluminium.
Alloy 2017A is commonly used for:
